IMPROVEMENT IN MEAS'URAING-CAN FOR LIQUIDS.

The Schedule referred to in these Letters 'Patent and rnakng part 0f the ame To whom it may concern Be it known that I, XVILLIAM BARRY, of Carthage, in the county of Jefferson, in the State of New York, have made a new and useful-Improvement in the Construction of Cans and Measures; and l do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of my improvement consists in providing cans, or other receptacles, in which are stored sii-, ups or molasses, for the retail trade of' dealers in those articles, with measures so constructed and arranged as to expedite the draught of the same for purchasers.

The time consumed in making draughts of sii-ups and molasses, in such quantities as are called f'or by purchasers, from ordinary casks, and suchl as are now generally used, and in the transfer of' such sirups to the receptacles provided `by purchasers, especially ii' such receptacles have narrow necks, is, as is well known, largely out-of` proportion to the value of such articles or the profit made upon their sale; and as they are usually stored in rooms of low temperature, the time consumed in making draughts is increased by that circumstance, and in winter, so sluggish is their Inove- Inent that it has passed into a proverb. Besides, it is frequently the case, that but one person is in attendance upon the business ofthe dealer, and the time devoted to this branch of' it is a mattei' ci' great inconvenience. It is to expedite this part of' the dealers business that I have made my improvement.

v In the drawings- Figure 1 is au elevation of the can and measure; Figure 2, 'avertical section of the same and the accessory parts; and

Figure 3, a section of' the plunger and of' some of its parts.

Like letters refer to like parts in all the figures.

The can A is made of tin, or other suitable material, closed at the top by the cover H, and set upon or attached to the base B, the whole mounted upon legs, or standards.

O-is the measure, also made of tin, or other suitable material, connected to the bottom ofthe can, the top of which measure being open, and of the same diameter of the opening to it through the bottom ofthe can, the measure passing through the base B.

fis the plunger, fitting the interior of' the measure, the plunger being formed otl two metal disks, with packing between them, the disks being connected together, and the proper pressure given to the packing, by screws.

The plunger is connected by the supports d to the tube d. l

F is the valve, secured to the lower end of the valverod G, which valve-rod moves freely in the tube ql.

D is an orice, or passage through the plunger, v

g isa spiral spring, the ends of which are attached to the handle E and to the thumb-piece on the upper end of the valve-rod.-

c is a stop on the tube, and limiting the upward movement ofthe tube, by coming in contact with the cover, to prevent the plunger being drawn ont of the measure.

c is the discharge-cock.

I will now proceed to describe the operation of' my improvement.

'lh'e' sirup or molasses is drawn, at a convenient time/from the casks in which they are purchased,

into the can A, there being an opening in the cover, H, provided with a lid. They are then ready for delivery to purchasers, and a draught of' them is made as follows:

The plunger, resting on the bott-om of' the measure C, is raised by the handle E. Simultaneously with the raising of' the plunger, the valve F will be pressed from its seat, as shown in lig. 3. This position ofthe valve is attained by forcing the valve-rod G downward, by apressure oi' the thumb of' the operator upon the thumb-piece before mentioned.

The sirup, in consequence of' this movement, will flow through the orifice D, to supply the vacuum underneath the plunger.

The cubical contents of the measure C being known, the'height to which the plunger must be raised, so that a required quantity may flow underneath the plunger, is indicated by graduation-marks and figures on the upper end ofthe tube (l, which marks and figures are shown in fig. 1.

When the gradnation-marks indicate the quantity required, the pressure is removed from the valve-rod, and the valve allowed, by the action of the spring, to return to its seat, as shown in iig. 2.

The plunger is then i'orced downward, andthe sirup or molasses discharged through the cock C into whatever receptacle is provided for the same.

Among the other advantages arising from the use of' my improvement is that of cleanliness,- as the measin'cis not, as is the case with the measures now generally used, exposed to the accumulation of insects, dirt, Sto and my improvement will be applicable and of utility in the draught of oils or any liquids that are sluggish in their flow.

What 1 claim as my invention, and desire to secure by Letters Patent, is-

l. The arrangement of the measuring-chamber, opening directly into the base, or bottom, and forming part of the can or other vessel with which it is employed, substantially as and for the purposes shown and set forth.

2. The combination, with the liquid-containing vessel and measuring-chamber, arranged as specified in preceding clause, ofthe plunger and valve located beneath said plunger, together with the rods for actuating the same, having their common bearing in the cover of said vessel, and arranged to operate as herein shown and described.

WM. BARRY.
